If output frequency reaches 01-03(P.3) * 08-14(P.182) and feedback value < target value * 08-07(P.175), and the
duration time exceeds 08-08(P.176) value, PID is considered abnormal and inverter will act according to
08-09(P.177) setting.
For example: 08-07(P.175)=60%, 08-08(P.176)=30s, 08-09(P.177)=0,01-03(P.3)=50Hz and 08-14(P.182), output
frequency reaches 50Hz, and feedback value is lower than 60% target feedback value for 30 seconds
continuously, alarm will trigger and inverter will stop freely.

If set 08-10 to 0, all 08-11, 08-12, 08-13 ,08-15 function are off. If 08-10 is not 0, turn on PID sleep function. If
deviation between actual feedback value and target feedback value is less than 08-10 sleep detection deviation for
08-11 sleep detection time, inverter will gradually reduce the output frequency. When inverter output frequency is
lower than 08-13 stop level, inverter will decelerate and stop. When feedback value is lower than 08-12 wake-up
level, inverter will start PID again
For example: 08-10(P.178)=5%, 08-11(P.179)=1.0s, 08-12(P.180)=90%, 08-13(P.181)=40Hz, 08-15(P.183)=0.5Hz, If
feedback value is greater than 95% and less than 105% of the target, inverter will reduce the output frequency
based on 0.5Hz per second. When inverter output frequency is lower than 40Hz, inverter will decelerate and stop.
If feedback value is lower than 90% of the target, inverter will wake up and be controlled by PID again.
